I pick the ship that looks prettiest, I then find a commander and other ships that seem to work with it, and then I always add in squadrons because that's how I Star Wars.
I also have absolutely no idea whatsoever what is the meta. And, I have put NebBs in every Rebel build I have ever made since wave 1 (except one Akbar list, when I bought my first MC30), because that frigate is the sexiest ship in the game.
